Dont worry - I have owned bettas for 30 years and know what stressed ones look like. Mine are healthy, active and not stressed. I would not allow them to get that way. The babies actually seem like they enjoy each others company right now, hanging close to each other, but never flaring or showing aggression. If that changes as they grow, I will separate them. I have two at work in separate 2 gallon tanks that are next to each other. The only time they flare at each other is during feeding time. Otherwise they ignore each other.

I am enjoying having a reasonable conversation with you. You seem like you care a lot.

My Petco loves there fish sorry for your bad expeirences can not wait to see them as adults sorry did not know it was just while they are small I have a pretty active and healthy Betta I believe the tank size is right but territoral fish should not be that close to eachother.

My fish are tiny babies. They shouldn't really be in bigger tanks just yet anyway. They are easier to keep an eye on in the smaller tank. They are healthy and active. People can say whatever they want about tank size, but that doesn't make your fish healthier. You have yours in a 10 gallon - does that mean someone who has one in a 55 gallon has healthier fish than you? How you take care of them is what determines a fish's health. That thread is about small tanks, many of which are smaller than mine. Everyone know the boards opinion on tank size, you don't need to keep stating it over and over again. (not in a nice way, by the way)

I am not sure where you live, but here in NY, Petco doesn't give a crap about their bettas. When I picked up my 2 babies, there were 7 others on the shelf. 5 were dead in their cups. One had been dead a couple days because it was actually covered in fuzz. Next time I go into my petco, I will snap a few pictures for you.

I am not bashing the smaller tank many users agreed 5 gal dividing minumum and no offense but you are acting pretty ignorant my petco takes great care of their fish the cup excuse is used by everyone even people with .25 tanks those cups are a temparay are fish would cost a fortune without them how about a pair up I compare my ten gallon makes health ro your health and you are the one being rude frankly.

You get what you give. Smaller tanks don't mean unhealthy fish. Learn instead of just parroting what other people say. You want to see unhealthy, take a walk through petco and petsmart. If you think my fish are better off in those tiny cups on the pet store shelf, then you are really in trouble.
